The Kapp Putsch, also known as the Kapp–Lüttwitz Putsch, was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the Reichswehr, as well as nationalist and monarchist factions.

The Weimar Republic, officially known as the German Reich, was a historical period of Germany from 9 November 1918 to 23 March 1933, during which it was a constitutional federal republic for the first time in history; hence it is also referred to, and unofficially proclaimed itself, as the German Republic. The period's informal name is derived from the city of Weimar, which hosted the constituent assembly that established its government. In English, the republic was usually simply called "Germany", with "Weimar Republic" not commonly used until the 1930s.
